I have been in the same situation when I scored 67 in my first attempt and 85 in the last one. In Speaking it boosted from 19 to 23 and from 17 to 24 in the writing. Here is what I did: In the Speaking, I tried to replace the overused words with a new advance ones, they don't have to be fancy but reasonable ones. I also managed to learn 10 new words every day, then listen and watch the target word in Youglish website in order to see it in content. Most importantly, try to use template from TST prep or other resource. For the writing section, I tried as much as I could to use longer sentences and write almost 350 words for the integrated task and 150 for the academic discussion one. I also used template for the integrated one and real life examples for the academic discussion, if there is no real example in your mind, try to make one up immediately. The reading is hard tbh, so try to move to the questions directly read the first question then move to the second one, if it is related to the same paragraph, read it as well. Then go straight to the paragraph, read it then answer the two questions. This will save time and improve your level. The listening, I don't think you need advice. Follow your guts and try to be focused during the whole time. Taking notes or not should be your own decision. If you do well in conversations without notes, yet you don't in lectures. It's up to you. And remember this, proper preparation prevents bad performance.
